High-efficiency perfume capsules

ABSTRACT

The present application relates to high efficiency particles and compositions, such as consumer products, comprising such high efficiency particles as well as processes for making and using such high efficiency particles and compositions comprising such high efficiency particles. Such high efficiency particles and compositions provide enhanced benefit agent delivery to a situs that is treated with such high efficiency particles and compositions.

FIELD OF INVENTION

The present application relates to high efficiency encapsulates and compositions, such as consumer products, comprising such high efficiency encapsulates as well as processes for making and using such high efficiency encapsulates and compositions comprising such high efficiency encapsulates.

BACKGROUND OF THE INVENTION

Benefit agents, such as perfumes, silicones, waxes, flavors, vitamins and fabric softening agents, are expensive and/or generally less effective when employed at high levels in consumer products, for example, personal care compositions, cleaning compositions, and fabric care compositions. As a result, there is a desire to maximize the effectiveness of such benefit agents. One method of achieving such objective is to improve the delivery efficiencies of such benefit agents. Unfortunately, it is difficult to improve the delivery efficiencies of benefit agents as such agents may be lost do to the agents' physical or chemical characteristics, or such agents may be incompatible with other compositional components or the situs that is treated.

One method of improving the delivery efficiency of a benefit agent is to encapsulate such benefit agent. While such efforts may improve the delivery efficiency of the benefit agent, further delivery efficiency improvements are desired as encapsulated benefit agents may be lost before or after they are applied to the situs of interest due to factors such as mechanical or chemical interactions, for example the action of wash and or rinse liquors, and/or charge interactions. In certain applications, the deposition of encapsulated benefit agents is improved by coating the encapsulated benefit agent with a polymers. In general, such polymer coating improves the deposition of the encapsulates. However, when multiple surfaces are treated simultaneously, for example, a load of laundry containing a variety of fabrics, each surface is typically treated to a different degree (more or less benefit agent being delivered). For cases where the benefit agent is a perfume, the different treatment levels on the different fabrics of a wash load, can lead to too strong odor on some fabrics and to too weak an odor on other fabrics. Applicants recognized that the source of the unequal treatment problem was primarily due to preferential encapsulate deposition that was driven by the polymeric deposition aid. Thus what is needed are encapsulated benefit agents that have a high and even deposition profile across multiple different surfaces.

In the present application, Applicants disclose encapsulated benefit agents and specific classes of amine containing polymers that, when combined, provide a high and even deposition profile across multiple different surfaces, for example, hair, skin, and multiple fabrics such as cotton, high surface cottons, polycotton and polyester.

SUMMARY OF THE INVENTION

The present application relates to high efficiency encapsulates and compositions, such as consumer products, comprising such high efficiency encapsulates as well as processes for making and using such high efficiency encapsulates and compositions comprising such high efficiency encapsulates.

Perfume Microcapsule

It is advantageous to add perfume in the form of encapsulated perfume ingredients to a composition, as the encapsulation of the perfume ingredients allows a controlled and eventually targeted release of the perfume ingredients. Perfume ingredients, are the individual chemical compounds that are used to make a perfume composition. A perfume composition comprises one or more perfume ingredients, the choice of type and number of ingredients being dependent upon the final desired scent. The present invention may comprise perfume microcapsules. It is well known to those skilled in the art, that perfume microcapsules release perfume ingredients during handling of fabrics and during the in wear process, providing improved longer lasting freshness on fabrics, as compared to the addition of neat perfume alone. The release of the perfume ingredients is triggered by mechanical stress breaking the capsule wall and allowing the diffusion of the encapsulated perfume ingredient.

A perfume microcapsule comprises a capsule surrounding a core, that core comprising perfume ingredients. The capsule can be made of a number of materials, but most preferred is cross-linked melamine formaldehyde. The capsule wall material may comprise a suitable resin including the reaction product of an aldehyde and an amine, suitable aldehydes include, formaldehyde. Suitable amines can include those selected from the group comprising melamine, urea, benzoguanamine, glycoluril, and mixtures thereof. Suitable melamines can include those selected from the group comprising methylol melamine, methylated methylol melamine, imino melamine and mixtures thereof. Suitable ureas can include those selected from the group comprising dimethylol urea, methylated dimethylol urea, urea-resorcinol, and mixtures thereof.

In the context of the present invention, any suitable perfume ingredient may be used. Those skilled in the art will recognize suitable compatible perfume ingredients for use in the perfume microcapsules, and will know how to select combinations of ingredients to achieve desired scents.

In one aspect, at least 75%, 85% or even 90% of said perfume microcapsules may have a particle size of from about 1 microns to about 80 microns, about 5 microns to 60 microns, from about 10 microns to about 50 microns, or even from about 15 microns to about 40 microns.

At least 75%, 85% or even 90% of said perfume microcapsules may have a particle wall thickness of from about 60 nm to about 250 nm, from about 80 nm to about 180 nm, or even from about 100 nm to about 160 nm.

The liquid fabric softening compositions of the present invention comprise from 0.05% to 0.8% by weight of the liquid fabric softening composition of encapsulated perfume ingredients, present in the form of a perfume microcapsule. This amount is necessary to ensure sufficient perfume is deposited onto the fabrics. Perfume and perfume microcapsules are washed away during the laundry process. Therefore, it is important to have enough perfume in the liquid fabric softening composition to take account of the inevitable loss, yet still have sufficient deposition onto fabrics.

In one aspect, said perfume microcapsule may be spray dried.

The liquid compositions of the present invention may comprise a rheology modifier. The rheology modifier may be selected from the group consisting of non-polymeric crystalline, hydroxy-functional materials, polymeric rheology modifiers which impart shear thinning characteristics to the aqueous liquid matrix of the composition. In one aspect, such rheology modifiers impart to the aqueous liquid composition a high shear viscosity, at 20 sec⁻¹ shear rate and at 21° C., of from 1 to 7000 cps and a viscosity at low shear (0.5 sec⁻¹ shear rate at 21° C.) of greater than 1000 cps, or even 1000 cps to 200,000 cps. In one aspect, for cleaning and treatment compositions, such rheology modifiers impart to the aqueous liquid composition a high shear viscosity, at 20 sec⁻¹ and at 21° C., of from 50 to 3000 cps and a viscosity at low shear (0.5 sec⁻¹ shear rate at 21° C.) of greater than 1000 cps, or even 1000 cps to 200,000 cps. Viscosity according to the present invention is measured using an AR 2000 rheometer from TA instruments using a plate steel spindle having a plate diameter of 40 mm and a gap size of 500 μm. The high shear viscosity at 20 sec⁻¹ and low shear viscosity at 0.5 sec⁻¹ can be obtained from a logarithmic shear rate sweep from 0.1 sec⁻¹ to 25 sec⁻¹ in 3 minutes time at 21° C. Crystalline hydroxyl functional materials are rheology modifiers which form thread-like structuring systems throughout the matrix of the composition upon in situ crystallization in the matrix. Polymeric rheology modifiers are preferably selected from polyacrylates, polymeric gums, other non-gum polysaccharides, and combinations of these polymeric materials.

Generally the rheology modifier will comprise from 0.01% to 1% by weight, preferably from 0.05% to 0.75% by weight, more preferably from 0.1% to 0.5% by weight, of the compositions herein.

Structuring agents which are especially useful in the compositions of the present invention may comprise non-polymeric (except for conventional alkoxylation), crystalline hydroxy-functional materials which can form thread-like structuring systems throughout the liquid matrix when they are crystallized within the matrix in situ. Such materials can be generally characterized as crystalline, hydroxyl-containing fatty acids, fatty esters or fatty waxes. In one aspect, rheology modifiers include crystalline, hydroxyl-containing rheology modifiers include castor oil and its derivatives. In one aspect, rheology modifiers include may be hydrogenated castor oil derivatives such as hydrogenated castor oil and hydrogenated castor wax. Commercially available, castor oil-based, crystalline, hydroxyl-containing rheology modifiers include THIXCIN™ from Rheox, Inc. (now Elementis).

Other types of rheology modifiers, besides the non-polymeric, crystalline, hydroxyl-containing rheology modifiers described heretofore, may be utilized in the liquid detergent compositions herein. Polymeric materials which provide shear-thinning characteristics to the aqueous liquid matrix may also be employed.

Suitable polymeric rheology modifiers include those of the polyacrylate, polysaccharide or polysaccharide derivative type. Polysaccharide derivatives typically used as rheology modifiers comprise polymeric gum materials. Such gums include pectine, alginate, arabinogalactan (gum Arabic), carrageenan, gellan gum, xanthan gum and guar gum.

If polymeric rheology modifiers are employed herein, a preferred material of this type is gellan gum. Gellan gum is a heteropolysaccharide prepared by fermentation of Pseudomonaselodea ATCC 31461. Gellan gum is commercially marketed by CP Kelco U.S., Inc. under the KELCOGEL tradename.

A further alternative and suitable rheology modifier include a combination of a solvent and a polycarboxylate polymer. More specifically the solvent may be an alkylene glycol. In one aspect, the solvent may comprise dipropylene glycol. In one aspect, the polycarboxylate polymer may comprise a polyacrylate, polymethacrylate or mixtures thereof. In one aspect, solvent may be present, based on total composition weight, at a level of from 0.5% to 15%, or from 2% to 9% of the composition. In one aspect, polycarboxylate polymer may be present, based on total composition weight, at a level of from 0.1% to 10%, or from 2% to 5%. In one aspect, the solvent component may comprise mixture of dipropylene glycol and 1,2-propanediol. In one aspect, the ratio of dipropylene glycol to 1,2-propanediol may be 3:1 to 1:3, or even 1:1. In one aspect, the polyacrylate may comprise a copolymer of unsaturated mono- or di-carbonic acid and C₁-C₃₀ alkyl ester of the (meth) acrylic acid. In another aspect, the rheology modifier may comprise a polyacrylate of unsaturated mono- or di-carbonic acid and C₁-C₃₀ alkyl ester of the (meth) acrylic acid. Such copolymers are available from Noveon Inc under the tradename Carbopol Aqua 30®.

In the absence of rheology modifier and in order to impart the desired shear thinning characteristics to the liquid composition, the liquid composition can be internally structured through surfactant phase chemistry or gel phases.
